The Adverse Reaction Tracking package (ART) needs to be
able to check for the existence of the ALLERGY/ADVERSE REACTION entry in the B
cross reference in the Generic Progress Notes Title (#121.2) file. The ART
v4.0 post-init routine will change the .01 value of this File 121.2 entry to
ADVERSE REACTION/ALLERGY. After ART v4.0 is installed, ART will check for the
existence of the new value in the B cross reference of File 121.2.
Also, ART needs to do a direct global read of the second piece of the zero
node of this File 121.2 entry to determine the PROGRESS NOTE TYPE value.
